Ru(II) and Os(II) mixed-chelates derived from imidazole-4,5-dicarboxylic acid and 2,2'-bipyridine as colorimetric sensors for anions: synthesis, characterization and binding studies.
TLDR
Cyclic voltammetry (CV) measurements carried out in acetonitrile have provided evidence in favour of anion-dependent electrochemical responses of 1 and 2 with F(-) and AcO(-) ions. Expand
Near-Unity Photoluminescence Quantum Efficiency for All CsPbX3 (X=Cl, Br, and I) Perovskite Nanocrystals: A Generic Synthesis Approach.
In a generic synthesis approach, all three CsPbX3 (X=Cl, Br and I) perovskite nanocrystals having near unity quantum yields is reported. This has been achieved by injecting the desired amount ofExpand
Synthesis, structural characterization, photophysical, electrochemical, and anion-sensing studies of luminescent homo- and heteroleptic ruthenium(II) and osmium(II) complexes based on
TLDR
It is evident that in the presence of excess of anions deprotonation of the imidazole N-H fragment(s) occurs in all cases, an event which is signaled by the development of vivid colors visible with the naked eye. Expand
Synthesis, characterization, photophysical, and anion-binding studies of luminescent heteroleptic bis-tridentate ruthenium(II) complexes based on 2,6-bis(benzimidazole-2-yl)pyridine and
TLDR
The absorption spectra, redox behavior, and luminescence properties of the ruthenium(II) complexes have been thoroughly investigated, and it has been observed that the metalloreceptors act as sensors for F(-, AcO(-), and to some extent H(2)PO(4)(-). Expand
Monometallic and bimetallic ruthenium(II) complexes derived from 4,5-bis(benzimidazol-2-yl)imidazole (H3Imbzim) and 2,2'-bipyridine as colorimetric sensors for anions: synthesis, characterization,
TLDR
Cyclic voltammetry studies carried out in acetonitrile provided evidence of an anion-dependent electrochemical response with F(-) and AcO(-), and made complex 2 a suitable lifetime-based sensor for anions. Expand
A trimetallic mixed Ru(II)/Fe(II) terpyridyl complex with a long-lived excited state in solution at room temperature.
TLDR
Remarkably, the trimetallic complex having an Fe(II) terpyridyl center also has a long-lived excited state, despite the fact that low-energy iron-localized excited states exist on the complex. Expand
A terpyridyl-imidazole (tpy-HImzPh3) based bifunctional receptor for multichannel detection of Fe2+ and F- ions.
TLDR
Both the anion and cation binding properties of the receptor were thoroughly investigated in dimethylformamide-acetonitrile solution using absorption, emission, and (1)H NMR spectral studies which revealed that the receptor acts as a sensor for both F(-) and Fe(2+). Expand
Synthesis, structural characterization, and photophysical, electrochemical, intercomponent energy-transfer, and anion-sensing studies of imidazole 4,5-bis(benzimidazole)-bridged Os(II)Os(II) and
TLDR
Cyclic voltammetry measurements carried out in acetonitrile have provided evidence in favor of anion-dependent electrochemical responses of the bimetallic metalloreceptors with F(-) and AcO(-) ions. Expand
Synthesis, structural characterization, and photophysical, spectroelectrochemical, and anion-sensing studies of heteroleptic ruthenium(II) complexes derived from 4'-polyaromatic-substituted
TLDR
Anion-induced lifetime quenching and/or enhancement make the receptors suitable lifetime-based sensors for selective anions, and Cyclic voltammetric measurements of the compounds carried out in acetonitrile have provided evidence in favor of anion-dependent electrochemical responses with F(-) and AcO(-) ions. Expand
Ruthenium(II) and osmium(II) mixed chelates based on pyrenyl-pyridylimidazole and 2,2'-bipyridine ligands as efficient DNA intercalators and anion sensors.
TLDR
The photophysical properties of 1 and 2 in acetonitrile indicate that the metal-to-ligand charge-transfer excited state is mainly centered in the [M(bpy)2](2+) moiety of the complexes and slightly affected by the extended conjugation of the pyrenylimidazole moiety. Expand
